is there any reason youre rushing this model or uping your modeling speed? personally what i know is that the faster you try to model this car the more inaccurate its going to get because most cars have very interesting surfaces and you will have to study the shapes for a while so you can understand it i know this because the kleemann im modeling i had to redo it about 4 or 5 times cause every time i saw the real car i noticed something i didnt see before. but hey its really up to you.
